Generally speaking, the bank will adjust the credit limit according to the individual's card use. It is suggested that after applying for a credit card, you can spend it by credit card. In addition, you need to maintain your good credit and repay on time to avoid the adverse effects caused by overdue. Maybe it's because you didn't spend much money after opening the card. The bank thought that your credit limit could not be used up, so it reduced your credit limit. If the landlord is still worried, you can call the customer service of the bank where you handle the card to ask about the situation, or go to the website of I love the card to see if anyone else has answered the same question as you. I hope my answer can help the landlord!
